Closeup of Plate

Caption

The plating experiment in this image shows how yeast strains vary in resistance to a drug. Different strains (horizontal rows) were grown at cell densities that decrease from left to right. Sensitive strains only are capable of growing when plated at high density, while resistant strains are capable of growing even at low density. By studying very large populations of yeast, Princeton scientists have developed a new way to identify the hidden genetic material responsible for genetically complex drug resistance traits.
